Shortly after pod security coverage (preview) are deprecated, you’ll want already moved to help you Pod Cover Admission controller otherwise handicapped the fresh new function into one current groups utilising the deprecated element to execute upcoming group upgrades and become contained in this Azure assistance.

To change the protection of one’s AKS class, you could limitation what pods shall be arranged. Pods one to request information that you do not allow are unable to run in the brand new AKS people.

AKS preview has actually come towards the a self-services, opt-within the foundation. Previews are offered “as well as” and you will “just like the available,” and they’re omitted on the provider-level agreements and you will limited promise. AKS previews are partially protected by customer support for the a best-energy basis. As a result, these features commonly designed for development fool around with. To find out more, see the pursuing the help stuff:

Before starting

This article assumes on which you have a current AKS class. If you’d like an AKS team, understand the AKS quickstart utilizing the Blue CLI, having fun with Azure PowerShell, or by using the Azure portal.

Need the newest Blue CLI variation dos.0.61 or later hung and you will set up. Work at az –version to find the adaptation. If you want to setup or improve, look for Create Blue CLI.

Set-up aks-examine CLI extension

To use pod security policies, you would like the brand new aks-examine CLI extension version 0.cuatro.step one or higher. Establish new aks-preview Azure CLI extension utilising the az extension create demand, up coming seek one available standing using the az extension upgrade command:

Check in pod defense coverage function merchant
